Bioavailability: Why IV Outperforms Oral Supplements

When you swallow a vitamin or supplement, it passes through your digestive system before any of it reaches your cells. Gastrointestinal absorption rates for common nutrients are variable and often limited — oral Vitamin C, for example, reaches a ceiling due to intestinal uptake capacity (Padayatty et al., Ann Intern Med, 2004). By contrast, IV delivery bypasses the GI tract entirely, achieving 100% bioavailability directly in your bloodstream.

This pharmacokinetic advantage is clinically meaningful. IV Vitamin C achieves plasma concentrations 70–100 times higher than oral supplementation at equivalent doses. IV magnesium reaches intracellular concentrations oral supplements cannot. Glutathione, which has very poor oral bioavailability, works systemically only when delivered IV.

At Vitality Texas, every IV and IM protocol is physician-supervised by Dr. Jaqua. Your formula is personalized to your labs, symptoms, and goals — not a one-size-fits-all menu item.

Who Benefits from IV Therapy?

IV therapy is physician-supervised at Vitality Texas and appropriate for a wide range of patients. Common presentations that Dr. Jaqua evaluates for IV micronutrient therapy include:

• Persistent fatigue that does not resolve with adequate sleep — often associated with B-vitamin or magnesium depletion
• Recovery from illness, surgery, or intense physical training — where accelerated micronutrient restoration is clinically indicated
• Acute dehydration from heat, alcohol consumption, or illness — where oral rehydration is too slow or poorly tolerated
• Patients on GLP-1 / weight loss programs who need micronutrient support during caloric restriction
• Athletes seeking IV nutritional support for recovery and hydration maintenance
• Patients with chronic low energy, poor immune response, or documented micronutrient deficiencies

IV therapy at Vitality Texas complements our broader wellness programs. Many patients combine IV nutritional support with their medical weight loss program or their peptide therapy program for a comprehensive approach to cellular optimization.

If you are unsure whether IV therapy is appropriate for you, a free consultation with Dr. Jaqua is the right first step.

NAD+ IV Infusion: Cellular Energy and Cognitive Support

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell, essential for mitochondrial energy production, DNA repair, and cellular signaling. NAD+ levels decline with age — IV delivery supports cellular energy and metabolic function at concentrations difficult to achieve with oral supplementation (Rajman et al. Cell Metabolism. 2018;27(3):529–547).

Vitality Texas offers NAD+ both as an IV infusion (administered in-clinic) and as a subcutaneous injectable program for home use. The IV route delivers higher plasma concentrations in a single session; the injectable program is designed for convenient ongoing support. Many patients use both modalities — IV sessions periodically and injectable NAD+ in between.
